Islamic State torches oil field snear Tikrit as Iraqi soldiers advance

The outcome of the battle for Tikrit, best known as the home town of executed Sunni president Saddam Hussein, will determine whether and how fast the Iraqi forces can advance further north and attempt to win back Mosul, the biggest city under Islamic State rule. Tehran, not Washington, has been the key player in the current offensive, with Iranian Revolutionary Guard general Qassem Soleimani seen directing operations on the eastern flank, and Iranian-backed militia leading much of the operation.
